It used to be a pain to hunt down your favorite extensions every time you reinstall Firefox. Mozilla's recently launched Collections make it easy, so we've assembled a few easy-to-install collections of our favorite Firefox helpers.

How can you make the most of our recommended add-on collections? Get yourself a Mozilla account, or sign in if you've got one already, and add the Lifehacker packs as "favorites." Then you'll be "subscribed" to them (yes, inconsistent terminology, but it works). You can then quickly install some or all of our chosen extensions from each collection's site with a few browser clicks.

Better still: Install the Collector add-on, sign in through it, and your subscriptions will be available for downloading even faster. Additionally, if we add items to these packs as we discover great and useful add-ons, you'll be notified and have an easy route to install them.

We're also opening the floor to anyone who's got a solid suggestion or two to include in these packs. Got a web development tool that's indispensible to your job? Know a multimedia add-on that's scads than anything else? Tell us which extensions you'd like to see, in which packs, and we'll review your submissions and consider them for our evolving, changing, work-in-progress collections.
